WebJun 28, 2024 · Then, you want to find the minimum of sin 2 k x + cos 2 k x = ( 1 − cos 2 x) k + ( cos 2 x) k over all x ∈ R. Because cos is surjective on [ − 1, 1], it is equivalent to minimize f ( u) = ( 1 − u) k + u k over all u ∈ [ 0, 1]. For that, you can differentiate the (smooth) function f.
